v Specification of Letters Patent .P t t d O t 12 1915 Application filed January 3. 1913. SeriaLNo. 741,764.-

To all whom it mag/concern I Be it known that L'JOSEPHDAIN, a citizen of the United States, residing at Moline, in

cation, reference being accompanying drawing,

the ,county ofRock- Island and State of Illinois, have invented certain new and useful Improvements in Tongue-Trucks for Harvesters, of which thefollowing is a specifihad therein to the My invention relates to tongue tru cks'for harvesters and other agricultural imple-' ments, upon which the stubtongue of an implement is supported, and my object is to provide a' tongue truck by which the implement can be readily steered.

A further object of my invention is the novel arrangement of the parts by which the I Referring to the drawings in which simitongue-truck will be deflected to a greater degree than the pole tongue when turning the implement with which it is used.

lar numerals indicate identical parts- Figure 1 is a side elevation of my improved truck in part section with the-stub and pole tongues brokenaway. Fig, 2-is a plan view of Fig. 1; Fig 3 is a plan view showing the relative position of the part .when making a turn. .Figs. 4, 5 and 6 are views similar to Figs. -1, 2, and-3 to'illustrate a modification of-my device.

A pole tongue 1 has secured to it a casting 2 having rearwardly projecting arms 3"between which is horizontally pivoted the for- Y ward end of 'a rearwardly extending member .4, Which'may be considered as part of the pole tongue 1 the member 4 is vertically" pivoted to a stub tongue 5 which is shown broken but-which maybe attachedto any of various. machines and implements. The

connection of the pole tongue with the memher 4 is flexible vertically to allow the truck to travel over uneven ground .without strain :-.-u:pon the horses pulling the machine. The

. vertical pivot by which the member 4 is secured to the stub tongue5 consists of a bolt 6 projected upwardly through a spacingblock 7 and through the stub tongue 5 and plates 8 and 9 on the upper and lower sides respectively of the stub tongue 5, and secured in placeby a suitable nut.

' Journaled in the forward part of the stub tongue 5 is the vertical portion 10 of a crank standard which has a portion 11 at an angle to the portion 10, and a portion 12 bent downwardly at an angle to the portion 11 to form a crank, the portion12 of which passes through and engages with a slot 13 in the member 4;; below the member 4 the standard extends downwardly, its end portion 14 bemg horizontal and pivotally supported in a "bearing 15 preferably forming a part oat-a tubular member 16, through which the axle 17 passes, 'the latter being supported by wheels 18 which may be flanged, as shown,

or otherwise formed. I provide a collar 19 on the crank standard to limit the down ward movement of the pole tongue 1 thereon.

When the pole tongue 1 is moved laterally for the purpose of changing the direction of travel of the machine, the crank standard,

having its vertical pivot on the stub tongue,

is deflected to a greater degree laterally than 'ment of the former with the crank standard being greater'than the distancebetween the pivotal connection of the crank stand: ard on the stub tongueandthe point ot engagement of the crank standard and pole tongue gives a long leverage which causesan instant response'of the truck to the move-' ment of the pole tongue. As shown inthe drawings the pivot ofthe crank standard on the stub tongue is forwardly of the vertical axis of the truck axle. The horizontal pivot of the crank standard on the truck per mits the latter to follow the undulations-of the'ground, and the assembled-relation of the parts of my invention. practically eliminates the liability of overturning the truck when changing the direction of travelof the machine.

In the modification shown in Figs. 4, 5,

6, the pole tongue 1 is pivoted to the'forward end of the stub tongue 5, forward of the pivot of the crank standard thereon; the

, portion11 of the crank standard-extends rearwardly and has the portion 12 bent downwardly at an angle to the portion. 11

and engaging with the rear end of the poletongue 1 through 'aslot 13 therein. I The end portion 14 of the crank standard is pivotally supported in the bearing 15 in'the-tubular member 16 in which the axle 17 is mounted,

the portion 12 of the crank standard between the portions 11 and 1t thereof being perpendicular. The relative positionof the parts is the reverse of the relative position shown in Figs. 1, 2, and 3, the action-and results are similar however.

'hat I claim is-- V 1 1. A tongue truck for harvesting machines or the like, having in combination an axle having supporting wheels, a stub tongue, a standard pivoted on the stub tongue and axle and adapted to be swung laterally and having an intermediate portion bent to form .1 crank, and a pole tongue pivoted on the stub tongue and engaging with the crank portion of the standard. 1

2. A tongue truck for harvesting machines or the like, comprising an axle having supporting wheels, a stub tongue, a standard pivoted on the stub tongue and axle and bent intermediateitsends to form a crank, and a pole tongue pivoted on the stub tongue and having a sliding engagement with the crank portion of the standard.

3. A tongue truck for harvesting machines or the like having combination an axle having supporting wheels, a stub tongue, a

standard pivoted on the stub tongue and axle and bent intermediate its ends to form a crank, and a pole tongue pivoted to the stub tongue to swing laterally and engaging with the crank portion of the standard, the distance between the pivot of the pole tongue on the stub tongue and the point of engagement of the pole tongue with the crank portion of the standard decreasing as the pole tongue is swung laterally.

4. A tongue truck for harvesting machines or the like having in combination, an axle having supporting wheels, a stub tongue, a standard pivotally connecting said stub tongue and axle and bent intermediate its ends to form a crank, a pole tongue-pivoted on the stub tongue to swing laterally and having a sliding engagement with the crank portion of the standard, the distance between'the pivot of the poletongue on the stub tongue, and the point of engagement of the pole tongue with the crank portion of the standard decreasing as the pole tongue is swung laterally.
